By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some
other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network.
If you have an unusual network connection in which you are actually connected via xDSL but for which you confgure either
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router
will recognize that it needs to shape traffc slightly differently in order to give the best performance. Choosing xDSL or Other

Section 8 · Conlquration
This Wizard helps you add wireless devices to the wireless network.
The wizard will either display the wireless network settings to guide you through manual confguration, prompt you to enter
the PIN for the device, or ask you to press the confguration button on the device. If the device supports Wi-Fi Protected Setup
and has a confguration button, you can add it to the network by pressing the confguration button on the device and then
the on the router within 60 seconds. The status LED on the router will fash three times if the device has been successfully
added to the network.
There are several ways to add a wireless device to your network. A “registrar” controls access to the wireless network. A
registrar only allows devices onto the wireless network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup
button on the device. The router acts as a registrar for the network, although other devices may act as a registrar as well.

Section 4 · Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DIR-655 offers the following types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)
• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t
been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead
of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specifc MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a
more secure public key encryption system to ensure that only authorized network users can access the network.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-655. Read
the following descriptions if you are having problems. (The examples below are illustrated in Windows
®
XP. If you have
a different operating system, the screenshots on your computer will look similar to the following examples.)
1..Why.can’t.I.access.the.web-based.confguration.utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on
the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself.
Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 6.0 or higher
• Netscape 8 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using
a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may
not be on.
• Disable any internet security software running on the computer. Software frewalls such as Zone Alarm, Black Ice,
Sygate, Norton Personal Firewall, and Windows
®
XP frewall may block access to the confguration pages. Check the
help fles included with your frewall software for more information on disabling or confguring it.
77 B·Link BíR·G55 bser Manual
Section G · Troubleshootinq
• Confgure your Internet settings:
• Go to Start > Settings > Control.Panel. Double-click the Internet.Options Icon. From the Security tab,
click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings
button. Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three
times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address
bar. This should open the login page for your the web management.
• If you still cannot access the confguration, unplug the power to the router for 10 seconds and plug back in. Wait
about 30 seconds and try accessing the confguration. If you have multiple computers, try connecting using a different
computer.
2..What.can.I.do.if.I.forgot.my.password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back
to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a
paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process.
Wait about 30 seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is

Section G · Troubleshootinq
3..Why.can’t.I.connect.to.certain.sites.or.send.and.receive.emails.when.connecting.through.my.router?.
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and
Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
Note: AOL DSL+ users must use MTU of 1400.
To fnd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could
be another computer, or a URL.
• Click on Start and then click Run.
• Windows
®
95, 98, and Me users type in command (Windows
®
NT, 2000, XP and Vista
®
users type in
cmd) and press Enter.(or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
. ping.[url].[-f].[-l].[MTU.value]
Example: ping.yahoo.com.-f.-l.1472
7O B·Link BíR·G55 bser Manual
Section G · Troubleshootinq

You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a
fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example,
lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network

D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard,
the D-Link wireless family of products will allow you to securely access the data you want, when and where you want
it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and offce environments, and public areas such
as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more effciently. Increased mobility and the absence of cabling and other fxed infrastructure have proven
to be benefcial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop
and desktop systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.

What.is.Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi
uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or
offce network.
Why.D-Link.Wireless?

D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products.
D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your
network.
How.does.wireless.work?

Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point
B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks Wireless
Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless.Local.Area.Network.(WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access
point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an
indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal
can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school
campuses, airports, golf courses, and many other outdoor venues.
82 B·Link BíR·G55 bser Manual
Aµµendix A · wireless Basics
Wireless.Personal.Area.Network.(WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range
up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use
nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops,
speakers, and other devices that operate on batteries.
Who.uses.wireless?.

Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, offce,
business, D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, and etc
• Gets rid of the cables around the house
• Simple and easy to use

Small.Offce.and.Home.Offce
• Stay on top of everything at home as you would at offce
• Remotely access your offce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate offce space

Wireless technology is expanding everywhere not just at home or offce. People like the freedom of mobility and it’s
becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless
connection in public places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote
locations like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the frst time it could be quite a task not knowing where to
start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless
network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize.your.router.or.Access.Point

Make sure you place the router/access point in a centralized location within your network for the best performance. Try
to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home.
If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate.Interference

Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the
router/access point. This would signifcantly reduce any interference that the appliances might cause since they operate
on same frequency.

Aµµendix A · wireless Basics
Security

Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning
on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more DIR-655 wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect
to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in
Ad-Hoc mode to communicate.
